• ADC6/INT2/ACMPN1/AMP2-/PCINT5 – Bit 5
ADC6, analog to digital converter, input channel 6.
INT2, external interrupt source 2. This pin can serve as an External Interrupt source to the MCU.
ACMPN1, analog comparator 1 negative input. Configure the port pin as input with the internal pull-up switched off to avoid
the digital port function from interfering with the function of the analog comparator.
PCINT5, pin change interrupt 5.
• APM0+/PCINT4 – Bit 4
AMP0+, analog differential amplifier 0 positive input channel.
PCINT4, pin change interrupt 4.
• AMP0-/PCINT3 – Bit 3
AMP0-, analog differential amplifier 0 negative input channel. Configure the port pin as input with the internal pull-up
switched off to avoid the digital port function from interfering with the function of the analog amplifier.
PCINT3, pin change interrupt 3.
• ADC5/INT1/ACMPN0/PCINT2 – Bit 2
ADC5, analog to digital converter, input channel 5.
INT1, external interrupt source 1. This pin can serve as an external interrupt source to the MCU.
ACMPN0, analog comparator 0 negative input. Configure the port pin as input with the internal pull-up switched off to avoid
the digital port function from interfering with the function of the analog comparator.
PCINT2, pin change interrupt 2.
• PCINT1/MOSI/PSCOUT2B – Bit 1
MOSI: SPI master data output, slave data input for SPI channel. When the SPI is enabled as a slave, this pin is configured
as an input regardless of the setting of DDB1 When the SPI is enabled as a master, the data direction of this pin is controlled
by DDB1. When the pin is forced to be an input, the pull-up can still be controlled by the PORTB1 and PUD bits.
PSCOUT2B, output 2B of PSC.
PCINT1, pin change interrupt 1.
• PCINT0/MISO/PSCOUT2A – Bit 0
MISO, master data input, slave data output pin for SPI channel. When the SPI is enabled as a master, this pin is configured
as an input regardless of the setting of DDB0. When the SPI is enabled as a slave, the data direction of this pin is controlled
by DDB0. When the pin is forced to be an input, the pull-up can still be controlled by the PORTB0 and PUD bits.
PSCOUT2A, output 2A of PSC.
PCINT0, pin change interrupt 0.
